Endovascular Repair of an Aneurysm Arising from a Celiomesenteric Trunk

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Anatomic Variations

Background:

• Celiac axis (CA) aneurysms are rare, comprising 3.6-4% of visceral artery aneurysms, and carry a high risk of mortality.
• A celiomesenteric trunk (CMT) is an uncommon anatomic variation where the celiac and superior mesenteric arteries share a single origin, present in about 1% of individuals.
• Aneurysms occurring at the junction of these vessels within a CMT are exceptionally rare.

Observation:

• A 62-year-old woman presented with a celiac artery aneurysm associated with a celiomesenteric trunk.
• The patient underwent successful endovascular repair of the aneurysm.

Findings:

• The repair utilized a bare metal stent-assisted coil technique.
• The procedure achieved satisfactory results, confirmed at the 10-month follow-up.
• This represents the first reported instance of this specific endovascular approach for a CA aneurysm at a CMT.

Implications:

• This case highlights the feasibility and efficacy of endovascular repair for rare CA aneurysms in the context of a CMT.
• The successful outcome suggests this technique may be a viable alternative to open surgery for select patients.
• Further research and case reports are warranted to establish the long-term durability and broader applicability of this treatment modality.
